present tense, past tense, past participal

[aisog]

Can someone explain the past participal for me please.

When would this be used?

Example : begin ; began ; begun

Eample : see ; saw ; seen

Have you saw John ? ( for example)

have you seen John? .................

I saw him two minutes ago.

I seen him two minutes ago.

Is one of these sentences wrong and why?

Thanks in advance.
